[PATCH] sanitize the interface of graft_tree().
Old semantics: graft_tree() grabs a reference on the vfsmount before
returning success.
New one: graft_tree() leaves that to caller.
All the callers of graft_tree() immediately dropped that reference
anyway. Changing the interface takes care of this unnecessary overhead.
Idea proposed by Al Viro.
